Some may be of the opinion that one event can begin before another only by virtue of the existence of some event (a “witness”) which wholly precedes the other and does not wholly precede the one (and similarly for “ends before” and “does not abut”). Those would prefer $\mathbb{F}$ 0 to $\mathbb{F}$ as a model for observers' apprehensions of events. Since G is a functor from $\mathbb{M}$ to $\mathbb{F}$ 0, the current construction (restricted to $\mathbb{F}$ 0) remains applicable.This work supports (...) a claim that the psychologically fundamental temporal relationships are “wholly precedes”, “begins before”, “ends before” and “abuts”. But only in a very weak sense. Any other set of relationships which is interdefinable with this one, using only quantifier-free formulas in the definitions, could be used to define a category $\mathbb{F}$ ′ which is indistinguishable from $\mathbb{F}$ (because the same functions preserve and reflect the new relationships). This work equally supports the claim that those relationships are the psychologically fundamental ones, or the claim that it is just “wholly precedes” which is fundamental, and that we perceive “begins before” just by virtue of witnesses. But it refutes the claim that only “wholly precedes” is fundamental, and that we understand “begins before” only because we understand time as a linear ordering. (shrink)

Unethical business in India became a recognized phenomenon during the second World War. Academic/journalistic/legal concern with ethics has become visible only during the nineties. Corruption-of-the-poor and corruption-of-the-rich need to be distinguished - especially in the context of globalization. The danger of attributing unethical practices to system failure is recognized. It is also important to bring to bear on intellectual property rights the more fundamental principle of natural property rights. Consciousness ethics will be more crucial than just intellectual ethics.

Although we believe the results reported below to have direct philosophical import, we shall for the most part confine our remarks to the realm of mathematics. The reader is referred to [4] for a philosophically oriented discussion, comprehensible to mathematicians, of tense logic.The “minimal” tense logicT0is the system having connectives ∼, →,F(“at some future time”), andP(“at some past time”); the following axioms:(whereGandHabbreviate ∼F∼ and ∼P∼ respectively); and the following rules:(8) fromαandα → β, inferβ,(9) fromα, infer any substitution instance ofα,(10) fromα, (...) inferGα,(11) fromα, inferHα.A tense logic is a systemTwhose language is that ofT0and whose axioms and rules include (1)–(11). The axioms and rules ofTother than (1)–(11) are calledproperaxioms and rules.We shall investigate three systems of semantics for tense logics, i.e. three notions ofstructureand three relations ⊧ which stand between structures and formulas. One reads⊧αas “αis valid in.” A structureis amodelof a tense logicTif every formula provable inTis valid in.

BackgroundReducing the number of animals used in experiments has become a priority for the governments of many countries. For these reductions to occur, animal-free alternatives must be made more available and, crucially, must be embraced by researchers.MethodsWe conducted an international online survey for academics in the field of animal science (N = 367) to explore researchers’ attitudes towards the implementation of animal-free innovations. Through this survey, we address three key questions. The first question is whether scientists who use animals in (...) their research consider governmental goals for animal-free innovations achievable and whether they would support such goals. Secondly, responders were asked to rank the importance of ten roadblocks that could hamper the implementation of animal-free innovations. Finally, responders were asked whether they would migrate (either themselves or their research) if increased animal research regulations in their country of residence restricted their research.ResultsWhile nearly half (40%) of the responders support governmental goals, the majority (71%) of researchers did not consider such goals achievable in their field within the near future. In terms of roadblocks for implementation of animal-free methods, ~ 80% of the responders considered ‘reliability’ as important, making it the most highly ranked roadblock. However, all other roadblocks were reported by most responders as somewhat important, suggesting that they must also be considered when addressing animal-free innovations. Importantly, a majority reported that they would consider migration to another country in response to a restrictive animal research policy. Thus, governments must consider the risk of researchers migrating to other institutes, states or countries, leading to a ‘brain-drain’ if policies are too strict or suitable animal-free alternatives are not available.ConclusionOur findings suggest that development and implementation of animal-free innovations are hampered by multiple factors. We outline three pillars concerning education, governmental influence and data sharing, the implementation of which may help to overcome these roadblocks to animal-free innovations. (shrink)

An interpretation of Aristotle's modal syllogistic is proposed which is intuitively graspable, if only formally correst. The individuals to which a term applies, and possibly-applies, are supposed to be determined in a uniform way by the set of individuals to which the term necessarily-applies.

In his critique of aesthetic individualism, R.G. Collingwood provides an account of persons that anticipates the post-Wittgensteinians; notably, Peter Strawson, Daniel Dennett, and Annette Baier. According to this view, persons emerge in the midst of other persons. This process is always unfinished and ongoing throughout one's life. One difficulty with this perspective is the problem of firstness: if persons are essentially second persons or one's personhood is contingent upon other persons, how could there be a first person or early persons? (...) One solution to this problem is to employ the notion of family or community. This solution can be found in both Collingwood and Baier.After this discussion,we look at his autobiography for evidence of his own 'discoveries' of personhood. There is tension here because he was a rebel and a loner, but there were a few (but not many) good relationships that confirm or exemplify his view of persons in his own life. Also briefly addressed is how this view fits into his theories of history and art. (shrink)

How does aesthetic education begin and expand over time? David Hume’s idea of the narrow circle provides us with an answer when considering this question. He uses the narrow circle to explain how moral practices evolve, and by analogy, we can also use this conception to explain how aesthetic practices evolve. So I will first of all begin with a discussion of his essay “The Standard of Taste.”1 In this essay, Hume gives an excellent profile of the critic who has (...) the traits to generate the standard of taste: delicacy of taste or a delicate imagination; practice in a particular art; ability to make comparisons, free from prejudice; and good sense in exercising the former traits. He says that few are qualified... (shrink)

Jean-François Revel is the first philosopher to take food seriously and to offer a topology for food practices. He draws a distinction between different kinds of cuisine -- popular (regional) cuisine and erudite (professional) cuisine. With this distinction, he traces the evolution of food practices from the ancient Greeks and Romans, down through the Middle Ages, and into the Renaissance and the Modern Period. His contribution has been acknowledged by Deane Curtin who offers an interpretation of Revel’s conceptual scheme along (...) Platonic lines. In this essay the author reviews Curtin’s interpretation, finds it wanting in certain respects, and develops an alternative reading of Revel along Hegelian lines. This interpretation, the author believes, does greater justice to Revel’s topology for food practices. (shrink)

We show that the join of two classical [respectively, regular, normal] modal logics employing distinct modal operators is a conservative extension of each of them.

In lieu of an abstract, here is a brief excerpt of the content:Art's DetourA Clash of Aesthetic TheoriesS. K. Wertz (bio)Both John Dewey1 and Martin Heidegger2 thought that art's audience had to take a detour in order to appreciate or understand a work of art. They wrote about this around the same time (mid-1930s) and independently of one another, so this similar circumstance in the history of aesthetics is unusual since they come from very different philosophical traditions. What was it (...) about the climate of the times that led them to such an idea? Is it still viable today? Both philosophers thought that art's audience is not in a position to immediately appreciate works of art—that we are missing something for a direct appreciation or apprehension—so we must take a detour. Why the detours and what are they? Are the detours similar? And are Dewey and Heidegger right about this? The essay that unfolds below attempts to answer these questions.First a definition is in order so we know what the term "detour" means when I use it. What is a detour? It is a deviation from a direct course or the usual procedure; a roundabout way temporarily replacing part of a route; in other words, a bypass or a roundabout way to some destination. The Little Oxford Dictionary adds a different twist on my characterization: "a course that leaves and rejoins [the] direct route."3 Applying this idea to art, we can say that a detour describes an audience who ordinarily perceives an artwork is a legitimate beginning for an appreciation of it, but that course must be bypassed for another (conception) before it can rejoin the direct route (perception). In other words, perceptions in the aesthetic experience must be aided by conceptions—a decidedly Kantian stance taken by Dewey and Heidegger. Their illustrations make my interpretation plausible.One of Heidegger's examples is Van Gogh's painting of a pair of peasant boots.4 He selects this painting to illustrate his metaphysics, which centers around the notion of "equipment." Peasant boots are equipment in [End Page 100] the sense that they are worn or used; the mere thing (like shoes or boots in a store [exhibited] or a closet [in storage]) disappears in use and becomes equipment. Between equipment and mere things—these two categories of being—are artworks. They are pictorial representations of equipment (in Heidegger's illustration; a pair of shoes as mere things could be a pictorial representation, like an advertisement, but it wouldn't be the same). Through the painted boots, a world comes into focus—a network of meaning. The world Heidegger sees in the Van Gogh painting is captured in the following descriptions: "In the vicinity of the [art]work we were suddenly somewhere else than we usually tend to be…. The art work let us know what shoes are in truth" (ATCR 233). So the nature of art is still a question about the nature of representation for Heidegger: it is what the shoes disclose to us about human existence. As he says, it is not just merely a pair of shoes portrayed but shoes "from the dark opening of the worn insides … the toilsome tread of the worker stares forth" (ATCR 232). In other words, we see the difficult labor that this particular owner toiled with in her daily chores.In Tralbaut's book, he quotes Heidegger in a caption alongside the painting: "Engraving in the intimate obscurity of the hollow of a boot is the weariness of the steps of work. The rough and solid weight of the clog tells of the slow and obstinate trudge across the fields."5 Heidegger continues in the same vein:In the stiffly rugged heaviness of the shoes there is the accumulated tenacity of her slow trudge through the far-spreading and ever-uniform furrows of the field swept by a raw wind. On the leather lie the dampness and richness of the soil. Under the soles slides the loneliness of the field-path as evening falls. In the shoes vibrates the silent call of the earth, its quiet gift of the ripening grain and its unexplained self-refusal in the fallow desolation of... (shrink)

R. G. Collingwood (1889–1943) had several arguments that analyzed race in history and anthropology. These appear mainly in Roman Britain (both in theory and practice of history), The Idea of History, and The Principles of History. This latter work, which is fairly new to Collingwood scholarship (1999), contains the most important arguments. Collingwood argued that race is grounded in the historical process and this includes a people's environment, more so than genetics or evolution. He used the nature of art as (...) an example in his main argument. This spills over in his view of anthropology—in particular physical anthropology that was influenced by John Beddoe. His view is contrasted with Claude Lévi-Strauss who held that physical anthropology is at the forefront of social or cultural anthropology which follows its lead. Whereas Collingwood held that in studying blood types, skulls, and bones, 'one does not get inside the object or recreate its object inside itself.' Consequently, cultural anthropology will always provide the key to racial considerations. What is revealed is that emotions and rationality are the same across cultures; also, that superiority/inferiority claims about race are mythical and lead us into darkness and superstition. (shrink)

The persons who adapt to changes as may be necessary in the course of their existence not only survive in the struggle for existence but also thrive and enjoy their lives in the best possible way under the given circumstances. For, life consists in various relationships, which are in constant movement and change.Therefore dealing with change or change-management has got pivotal importance in all walks of humans’ lives. In order to facilitate smooth change all big and small inheritances have to (...) be shed off. Adaptation to change involves some amount of give and take. Before stepping into new shoes one has to remove old ones. Sticking to good or bad things of the past in some cases spoils the present. One should, therefore, be in a position to come out of the situation of status quoor inertia. In some cases our ego does not allow us to change. It forces us to remain in the state that we have been enjoying hitherto. If we are untouched by sense of exuberance and live a life of simplicity, we can break the fetters of ego. The crux of the problem lies in affecting the change of attitude towards the present state of affairs and performance of corresponding duty. The persons should realize that change in power, position, strength etc. is inevitable. So,they should be mentally and physically prepared for it. This can be conveniently achieved by developing adaptability to and management of change. (shrink)

I examine Nagarjuna’s averting an opponent’s argument, Paul Sagal’s general interpretation of Nagarjuna and especially Sagal’s conception of "averting" an argument. Following Matilal, a distinction is drawn between locutionary negation and illocationary negation in order to avoid errant interpretations of verse 29 The argument is treated as representing an ampliative or inductive inference rather than a deductive one. As Nagarjuna says in verse 30: "That [denial] of mine [in verse 29] is a non-apprehension of non-things" and non-apprehension is the averting (...) of arguments or "the relinquishing of all views." "Not making a proposition P" would be not speaking P or silence with regard to P and, as Sagal argues, not meaning a global linguistic silence. Such an interpretation would lead to attributing wholesale irrationalism to Nagarjuna-something I wish to avoid. (shrink)
